Subject: [PATCH V2 0/2] Add virtual hardware module

This patchset adds support for emulating virtual hardware with VKMS.
The virtual hardware mode can be enabled by using the following command
while loading the module:
        sudo modprobe vkms enable_virtual_hw=1

The first patch adds virtual hardware support as a module option. The
second patch adds new atomic helper functions for the virtual mode
and modifies the existing atomic helpers for usage by the vblank mode
This gives us two sets of drm_crtc_helper_funcs struct for both modes,
making the code flow cleaner and easier to debug.

This patchset has been tested with the igt tests, kms_writeback, kms_atomic,
kms_lease, kms_flip, kms_pipe_get_crc and preserves results except for
subtests related to crc reads and skips tests that rely on vertical
blanking. This patchset must be tested after incorporating the
igt-tests patch: https://lists.freedesktop.org/archives/igt-dev/2021-February/029355.html .
